The operating temperature range of Sanitary Butterfly Valve mainly depends on its design and the materials used, usually between -20℃ and 300℃.

Sanitary butterfly valves of different materials and structures can withstand different temperature ranges. For example, the standard operating temperature of sanitary butterfly valves made of stainless steel (such as 304 or 316L) is usually between -20℃ and 160℃. For sanitary butterfly valves with certain designs or special materials, such as electric sanitary butterfly valves, the operating temperature range can be extended to -29℃ to 300℃.

In addition, the applicable temperature range of pneumatic sanitary butterfly valves is generally -20℃ to 60℃, but this is also affected by factors such as the main material and the design of the actuator.

Therefore, when selecting a sanitary butterfly valve, it is necessary to determine the appropriate material and model according to the specific working environment and medium temperature.
